This is incorrect. "Multiculturalism" and mass immigration were always meant to destroy the host nation
The intent of flooding England with millions of Pakistanis, of packing Muslims into Scotland, of forcing every village to accept murderous invaders and the squalor and crime they bring with them...was not to make Great Britain a better place for those living in it
No, it was to destroy what remnants of "Merry Old England" were left after most of it had died in the Flanders, in the skies, or been taxed away under Churchill, Attlee, and Harold Wilson. Little remnants of what once was great about Albion remained, and those in charge wanted to destroy it. Hence the mass migration and all its awful consequences
Those who have ruled our Occidental lands for decades despise us. They hate our heritage, our history, our cultures. They hate God, they hate beauty, and they despise natural hierarchy.
What better way to destroy all that than with the all-pervasive feelings of humiliation and degredation that come with seeing millions of hostile foreigners imported at great cost, paid for with your tax dollars (which were taken from you at extortionate rates) go on to ruin your community, abuse the little girls, and be supported by the regime in doing so?
That was always the point of mass migration and multiculturalism
Integration has failed. Multiculturalism has failed. Mass immigration has failed.
All of it has failed.
